After four seasons and a 21-29 record, Frank Spaziani won’t return for another season, Boston College athletic director Brad Bates announced Sunday.

“A personnel decision of this magnitude affects many people and is never taken lightly, but I felt a chance was necessary,” Bates said in a statement.

Boston College finished the season 2-10 and lost its final four games, including Saturday’s season finale, 27-10, against N.C. State.

Prior to being named head coach in 2009, Spaziani spent 10 seasons as defensive coordinator and two as running backs coach at Boston College.

"It is with gratitude that we recognize the many contributions Coach Spaziani has made to Boston College during his 16 years in Chestnut Hill," Bates added. "He displayed unwavering dedication and loyalty to our institution and our football student-athletes, while consistently representing Boston College with class and dignity. He and his staff have devoted countless hours to our student-athletes and the BC community. We thank them and wish them well."

Bates said a search for Spaziani’s replacement will begin immediately.
